🐠【Parameter】Size: 4"x 4"(exact 100mm x 100mm) Diameter. Fits for 3/16"(4 mm） hose ID or 5/16"(8mm) hose ID. Color: White.
🐠【Fine bubble】 Oxygen stone refines the air output from the air pump into a particle bubble, which is smaller and denser, like the "atomization" effect, and the bubble size can be adjusted, and the different oxygenation amount can satisfy different use requirements
🐠【High dissolved oxygen rate]】 Compared with ordinary bubble stone, the nano bubble stone emits more bubbles, and the gas and the water surface are more widely contacted, which makes the dissolved oxygen amount larger
🐠【Quality Nanomaterials】: The nano-stone is sintered at high temperature. The material is sturdy and durable. It can be used for a long time and has better dissolved oxygen effect. When the bubble burst into the water, the sound is super quiet
🐠【Air pump wattage】 The weighs of air stone is 5.2oz/150g and is easily placed at the bottom of the fish tank, suitable for fresh water and salt water. It is driven by an air pump of 2 watts or more. PS: The deeper the water, you may need to use a larger wattage air pump to drive it
